Now, Sophie’s twin sister Ashleigh says she is devastated after her mobile phone, which contained hundreds of pictures of Sophie, was swiped from a pub table in Birkenhead, Merseyside.

More than 200 photos taken in the two years before Sophie died could now be lost forever.

Ashleigh said: “I just put the phone down for a minute on a table but then it was gone. I don’t even care about the phone – it’s just the photos that I want back.”

Heartbreaking: Peri reveals details of Sophie's final day

The twins’ mum, Peri Cawley has appealed for whoever took the phone to have a conscience and return it.

She has also spoken about her daughter's last day, suggesting Sophie waited to see her boyfriend Jake one last time before she passed away.

Peri said: "Because of all the drugs, she hadn't been speaking very well but, on the day she died, she asked for her phone and found the strength to call her boyfriend, Jake.

"Jake came straight away. I believe she was waiting to see him one last time before she let herself go. I held Sophie's hand as she passed away. She was surrounded by her family and she passed away knowing how much she was loved."

The cancer was confirmed after Sophie was admitted to hospital when her condition worsened, by which time it had spread to other parts of her body.
